4.3 Adjust Assistant commands
This operation checks whether the parameter settings are correct. For
parameters which are unspecified, the optimal values can be obtained by
performing “VISION TEST” here. The following adjustment procedure is
explained for cases where the “Mark Type” parameter in the Mark Type
Info. sub-window is set to “Fiducial”.
1 Select the mark data.
Move the cursor to the data you want to check on the Mark Info.
screen.
2 Open the Adjust Assistant screen.
Press the [F6] key to run the <2/1/B1 ADJUST ASSISTANT> command. The

Creating the PCB data
1. First select “CONVEYOR WIDTH” to adjust the conveyor width.
The conveyor width input box appears, so enter the PCB width (mm).
e
2. Press the emergency stop button and clamp the PCB on the conveyor
according to the selected PCB clamping method.
Reference
For details on the procedure for clamping the PCB on the conveyor, refer to “5. Clamping
the PCB” in this chapter and “8. Changing the conveyor unit setup” in Chapter 4.
4 Perform teaching for the mark.
When the cross cursor in the center of the vision monitor is aligned with
the appropriate position in the mark (see the table below), skip this
step. If not, perform teaching as follows.
1. Run the TEACH MARK command.
2. Manipulate the joystick so that the cross cursor on the vision monitor is
aligned with the appropriate position in the mark (see the table below),
then press the [ENTER] key.

5 Run the VISION TEST command.
Repeat this test several times. When no errors occur, the parameter settings
are appropriate. Advance to the next step. If an error occurs, adjust the
parameters with the procedure below.
1. Return to the Mark Info. screen with the EXIT command, and check that
the following parameters are set correctly.
Mark Type and MarkOutSize in the Mark Type Info. sub-
window
Shape Type and Surface Type in the Vision Info. sub-window
2. After checking the parameters, press the [F6] key to open the Adjust
Assistant screen again, then repeat Steps 4 to 5.
When no errors occur, move to the next step.
3. If an error still occurs, run the PARAM SEARCH command to find an
optimum threshold level.
4. After the optimum threshold level has been found, run “VISION TEST”
again.
When no errors occur, go to the next step.
If the optimum threshold level could not be obtained, run the CHK
THRESHOLD command.
A binary image will be displayed on the vision monitor according to
the current parameter settings as shown below. Adjust the threshold
level as suggested below, so that the mark image is clearly displayed.
